CONCRETIONARY PEDOFEATURES OF PROFILE-DIFFERENTIATED SOILS OF THE BESKYDY PRE-CARPATHIAN REGION (UKRAINE)

Abstract

The paper aimed to conclude that in profile-differentiated soils of Beskydy Pre-Carpathian region ortsteins are formed - specific Fe-Mn pedofeatures, which have clear outer contours, concentric inner structure with alternation of rings of rusty-brown and black color. Based on analyzed data the highest content of ortsteins is typical for elluvial horizon. In order to identify the genesis and elemental composition, a plate of tubular ortstein with a diameter of 1.2 cm selected from the Cg horizon has been made. It has been established that ortsteins in the profile-differentiated soils have been formed as a result of alternation of redox conditions and gley-eluvial, segregation processes of soil formation. The small ortsteins in the overiluvial part of the profile are the result of modern soil formation, and the large ones within the transition to the rock horizon are relict and connected with the early stages of soil formation in the Pre-Carpathian region of Ukraine.
